论文摘要
智能辅助系统可以导航盲人，但其中大多数只能给出非直觉的提示或效率低下的指导。基于计算机视觉和颤振的编码，本文提出了一种交互式系统，为盲人提供直观的空间认知。与基于语音提示的传统听觉反馈策略不同，本文首先引入了一种振动编码的反馈方法，该方法利用了触觉神经途径，并使用户能够与操纵辅助设备以外的对象进行交互。基于此策略，将采用基于RGB-D摄像机的可穿戴视觉模块，用于3D空间对象定位，这有助于准确的感知和在真实环境中的快速对象定位。目标盲人的实验结果表明，与主流语音及时反馈方案相比，纤维触觉反馈将任务的完成时间降低了25％。提出的对象定位系统提供了更直观的空间导航和舒适的耐磨性，以提供失明的帮助。
Intelligent assistive systems can navigate blind people, but most of them could only give non-intuitive cues or inefficient guidance. Based on computer vision and vibrotactile encoding, this paper presents an interactive system that provides blind people with intuitive spatial cognition. Different from the traditional auditory feedback strategy based on speech cues, this paper firstly introduces a vibration-encoded feedback method that leverages the haptic neural pathway and enables the users to interact with objects other than manipulating an assistance device. Based on this strategy, a wearable visual module based on an RGB-D camera is adopted for 3D spatial object localization, which contributes to accurate perception and quick object localization in the real environment. The experimental results on target blind individuals indicate that vibrotactile feedback reduces the task completion time by over 25% compared with the mainstream voice prompt feedback scheme. The proposed object localization system provides a more intuitive spatial navigation and comfortable wearability for blindness assistance.
